GEORGE W. ROLPH, OF TOLEDO, OHIO.

CAR-UNLO'ADER.

SPECIFICATION forming part of Letters Patent No. 267,593, dated November14, 1882.

Application filed September 20, 1882. (Model) To all whom it mayconcern:

Be it known that I, GEORGE WILLIAM ROLPH, of Toledo, in the county ofLucas and State of Ohio, have invented a new and Improved Oar-Unloader,of which the following is afnll, clear, and exact description.

My invention consists of the details of construction of certain parts ofa car-unloader for discharging earth from flat cars over the side bymeans of a kind of scraper to be operated by power from the locomotivedrawing it along against a guide-rail, located upon one side of the carto scrape off theload on the other side of the car, the said scraperbeing drawn along the train from one car to another, all as hereinafterdescribed.

I Reference is to be had to the accompanying drawings, forming part ofthis specification, in n hich similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a. plan view of a car-unloader constructed accordingto myinvention and being located on the deck of a flat car as in use;

Fig. 2 is a side elevation of the said car-unloader. Fig. 3 is atransverse section on the line m :r of Fig. 1, and Fig. 4 is aperspective view of the nose-piece of the machine and the frontguide-roller.

The machine consists essentially of the nosepiece a, base-timber c, andmold-board 1), arranged and connected together and provided withvertical carrying-rollers (Z and e, and the horizontal guide andfriction rollers f and g, to be drawn along the deck h and against theguide-rail i of a flat car by power from the 10- comotive, hitched tothe clevis It, say, by a wire cable, chain, or rope, one end of which ishooked into the clevis on the nose of the unloader and the other ishooked into the bumper of the locomotive, the brakes being set and thelocomotive uncoupled from thetrain and started, thus drawingthe scraperforward to scrape off the load of earth over the side of the caropposite to the guide-rail t". Heretofore the base-timber has beenfitted against the side of the sheet or plate of the mold-board andsecured by bolting through it and the moldboard, which has not proved asubstantial and satisfactory arrangement. I therefore propose to make acast-metal nosepiece, c, to constitute the front-end section of themold-board,

makingthereon'whatIcall a stirrup,j, which is a socket extension or lug,and fitting the end of the beam 0 in it, as clearly shown in Fig. 1,thus securingsaid beam and mold-board much more firmly together. Therear end of the nose-piece is cast with a rabbet, 7c, wherein the end ofthe mold-board is permanently riveted, so that the front surface isflush with the corresponding part of the nose-piece.

In the same lug that contains the socketl for the base-timber c, andbelow said socket, I make a slot or recess, m, in which to pivot the bara, in which the front carrying-roller, (I, is mounted for being adjustedby a hand-lever, 0, to set the roller, as required, for properlycarrying the front end of the machine when passing from car to car,which frequently vary to some extent in height, and thus require saidroller to be shifted up or down and set by the lever 0, standard p, andpin q.

In order. to enable me to locate other carrying-rollers d in boxes 8,attached to the under side of the beam 0, which is much better and moresubstantial than to fit said boxes to the side of the beam, I locate thesocket din the stirrup at such elevation in the nose-piece as will allowof so placing said boxes. The arrangement affords such substantialsupport to the boxes 8 that I am enabled to pivot the wheels onstud-pins t, which are firmly secured in the holes a of the boxes, andon which the wheels turn at the inner sides of the boxes, said wheels orrollers being held in position by heads of the pins. The saidarrangement also enables me to locate the guide-rollers f, which runagainst the rail i, under said beam 0, in boxes c, attached to the underside of said beam, enabling the rollers to run close down to the deck ofthe car along guide-beam i, which may thus resist the lateral thrust ofthe machine with less, strain upon its fastenings than if said wheelsworked higher up on it. The stirrupj is elongated from the lower endalong part w to the point 00, for the purpose of receiving a smallguide-roller g as near the point as possible, which I attach by fittingit in a box, y, and bolting the box in a recess, 2, formed in thecasting, the box being flush with the side of the stirrupj w, and sothat it can be readily taken out for repairs, when required. The frontend of the nose-piece is curved under or backward at c, in order toenable it to rise over the corners of the car in case it should fall solow in passing the gap between the cars as to touch the corner. The topguard, I), for riding along the top of guidet' to keep the nose up fromthe surface of the car-deck, is cast together with the nose-piece. and arib-brace, c, is provided for strengthening it.

I propose to use T-iron ribs (1 for stifiening the back of themold-board and connecting the stay-bars 0 instead of the angle-ironsheretofore used, and I propose to bend the tongues of the said ribsoblique to the head and parallel to the stay-bars rather than bend theends of the stay-bars, as shown in Fig. 1, which makesa much strongerconnection, because the tongues have the strength of their continuousconnection with their heads to resist the angular stress, whereas thebars have only the strength due to their breadth for that purpose.

The before-described elevation of the basebeam cis favorable to thearrangement of these stay-bars in the best position, for itenahles thelower ones to extend in about a straight line, from a point about ashigh on the mold-board as the under side of said beam, to said beam,said point on the mold-board being where the pressure is greatest, whilethe upper bars descend from near the top of the mold-board, where theresistance is less, to the top of the beam at an angle favorable to thedelivery of the thrust on the guide-wheels f and guide-rail t. Thebraces are arranged iilatwise with the tongues of the T-bars d, tofacilitate the connection with them, and they are twisted at d to litthe flat surface of the beam 0 and secured to it by one bolt, 0 passingthrough both upper and lower braces, said upper and lower braces be ingplaced one above another on the beam. 1 make the lower edgc,f, ot' thenose-piece to project a little beyond the edge 9 of the moldboard, andalso make the edge of the moldboard project farther in the samedirection than as heretofore made, together with a forward overhang ofthe top edge, It, and this latter I propose to increase from the frontrearward, for throwing downward the crest of the ridge of earth thrownup by the mold-board, which increases in height toward the rear of themold-board. At the rear end of the moldboard I make an extension of theupper edge rearward, at i, greater than at the bottom j, in about theproportion that the mold-board slopes backward from the edge of thecandeck, in order that the said upper part shall reach to the edge ofthe car and prevent the earth from falling back on the margin of thecar.

The inside carrying-wheels, c, are mounted in adjusting-bars a, the sameas the front carl'yingwlieel, (I, and have adjusting-levers 0, withstandards 1) and connecting-pins q, to set them from time to time tograduate the front edge, 9, of the mold-board to the car-deck.

The elew'isj is pivoted in a hollow boss, 5, cast together withthe'nose-picce a, and a crook is made in the clevis at m to pitch it inthe direction of the draft, which is toward the ccnter of thelocomotive, and would, for lack of the crook, draw out of line with theclevis. A stay-brace, a, extends backward from the clevis-pin to apoint, 0, where it.is bolted to the beam 0.

The lower edge, g, of the mold-board consists of a share bolted orriveted on the under side, and made to projectoutward nearlylevel withthe car-deck for shearing under the earth, the said share to be takenoil and removed when worn out.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
